We look at the division of 549485 by 78 
Let's see how many times 78 fits into 549485.

Step 1:
78 goes into 5 0 times with a remainder of 5.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Deduct 0 from 5 and we're left with 5.
Take the next digit (4) from the dividend and append it to 5, then repeat: 54 / 78

Moving on to step 2:
78 goes into 54 0 times with a remainder of 54.
Write down 0 as next digit of the result. 
Result so far: 0.0
Subtract 0 from 54 to get 54.
Take the next digit (9) from the dividend and append it to 54, then repeat: 549 / 78

Advancing to step 3:
549 divided by 78 is 7 with a remainder of 3.
Write down 7 as next digit of the result. 
Result so far: 7.0
Deduct 546 from 549 and we're left with 3.
Fetch the next digit (4) from the dividend, attach it to 3 and continue: 34 / 78

On to step 4:
78 can be fit into 34 0 times, resulting in a remainder of 34.
Use 0 as the next digit of our solution. 
Result so far: 70.0
Subtracting 0 from 34 leaves us with 34.
Take the next digit (8) from the dividend and append it to 34, then repeat: 348 / 78

Let's proceed to step 5:
The number 78 fits into 348 4 times, leaving a remainder of 36.
Use 4 as the next digit of our solution. 
Result so far: 704.0
Deduct 312 from 348 and we're left with 36.
Bring next digit (5) of the dividend behind the 36 and repeat the process: 365 / 78

Step 6:
365 divided by 78 is 4 with a remainder of 53.
Use 4 as the next digit of our solution. 
Result so far: 7044.0
Subtracting 312 from 365 leaves us with 53.
Since there are no more digits in the dividend, we add a zero to the remainder making it 530, and continue the process.

Step 7:
78 can be fit into 530 6 times, resulting in a remainder of 62.
Put 6 as the next digit of the answer. 
Result so far: 7044.6
If we take 468 away from 530, we end up with 62.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Let's proceed to step 8:
78 goes into 620 7 times with a remainder of 74.
The number 7 becomes the next digit in our result. 
Result so far: 7044.67
Subtracting 546 from 620 leaves us with 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

Advancing to step 9:
The number 78 fits into 740 9 times, leaving a remainder of 38.
Record the quotient 9 as the next digit in the result. 
Result so far: 7044.679
Subtract 702 from 740 to get 38.
Since there are no more digits in the dividend, we add a zero to the remainder making it 380, and continue the process.

Advancing to step 10:
78 can be fit into 380 4 times, resulting in a remainder of 68.
Put 4 as the next digit of the answer. 
Result so far: 7044.6794
If we subtract 312 from 380, we get 68.
Since there are no more digits in the dividend, we add a zero to the remainder making it 680, and continue the process.

Let's proceed to step 11:
680 divided by 78 is 8 with a remainder of 56.
Use 8 as the next digit of our solution. 
Result so far: 7044.67948
Subtract 624 from 680 to get 56.
Since there are no more digits in the dividend, we add a zero to the remainder making it 560, and continue the process.

Step 12:
78 can be fit into 560 7 times, resulting in a remainder of 14.
The number 7 becomes the next digit in our result. 
Result so far: 7044.679487
If we subtract 546 from 560, we get 14.
Since there are no more digits in the dividend, we add a zero to the remainder making it 140, and continue the process.

Moving on to step 13:
78 goes into 140 1 times with a remainder of 62.
Record the quotient 1 as the next digit in the result. 
Result so far: 7044.6794871
The remainder is 62 after subtracting 78 from 140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 620, and continue the process.

Advancing to step 14:
When dividing 620 by 78, we get 7 with a remainder of 74.
Write down 7 as next digit of the result. 
Result so far: 7044.67948717
Subtract 546 from 620 to get 74.
Since there are no more digits in the dividend, we add a zero to the remainder making it 740, and continue the process.

The final result is 7044.67948717 with a remainder of 7.4e-08.
